Question

Find the area of the shaded part in the figure given below.
(Take $\pi$ = $\frac{22}{7}$)
All the dimensions are in cm.

• A. 11
• B. 10.5
• C. 9.5
• D. 11.5

Answer 1

The correct option is B

10.5

Area of the shaded portion = Area of the square – Area of the circle

$=a^2–\pi r^2$ (where a is the side of the square and r is the radius of the circle)

$=7^2-\frac{22}{7}\times \frac{7}{2}\times \frac{7}{2}$

$=49-38.5$

$=10.5c{m}^2$
